CCS/TMS570LC4357: Problem in establishing the Connection for SCI-UART using the Terminal

Part Number: TMS570LC4357

Tool/software: Code Composer Studio

Hi,

As per the Hercules eval board tutorial (https://training.ti.com/hercules-how-tutorial-using-sci-uart-communication) data send through SCI should be receiving using the virtual COM port in XDS100V2 USB Jtag connector. However I am not able to see any data in terminal application using this method.

Does the communication can be established with the on board JTAG+UART port or do we need to have the TMS570LC4357 launchpad as used in this case https://e2e.ti.com/support/microcontrollers/hercules/f/312/t/670120?

Can we establish the above communication on the eval board kit, if yes then is there any special configuration we have to do?

Please Provide Inputs.

and

When we are sending the SCI data through the DMA, then is there any register, method or something with the help of which we can get the information about the packet that has sent? 

Regards,

  • Hello Shivam,

    Both HDK and Launchpad can output SCI message to terminal through the XDS100V2 or XDS110 USB cable.

    1. Make sure the SCI module is configured correctly

    2. In Terminal, select the right COM port

    3. Both sides (MCU, terminal) use the same UART settings (baudrate, and stop bit)

    There is an example for using DMA for SCI:
